Ok, I have had this Vector Underfolder for a couple weeks now and was able to put some rounds downrange with it so i thought I would leave some feedback for others who may be searching for info on the said ak.
I got it, cleaned it and went to the range, put 360 rounds of wolf downrange without a single malfunction.
A week later, a shootin buddy called and wanted to shoot. I grabbed the vector (uncleaned since the last outting) and some wolf 7.62x39 and rolled out. I put an additonal 180 rounds through it Not a single malfunction.
It shoots very nice. The build is very clean (nice rivet heads, nice wood hand guards, very worth the money. I think Atlanticfirearms.com has them for $589.00
here is the website: http://www.atlanticfirearms.com/programming/expand.asp?Prodid=8 sorry I don't know to make it "hot."
I also own an Arsenal, a polytech Legend, 3 polish underfolders, and a romanian wasr, so I based the above review with first hand experience with other ak varients that are out there. I am no expert on ak's though so take this as strictly opions from me. Hopefully this will help those of you who are thinking about getting the VECTOR.
Enjoy!
